Having paid his reckoning, he went to the door. As he was sallying out, a mounted officer dashed by at a headlong gallop; his horse was flecked with foam, and it was evident that he had ridden far and fast, on an important errand.

Having nothing to do until he should meet the peasant, Fergus followed the officer at a leisurely pace; and in five minutes came up with the horse, held by a soldier at the entrance gate of a very large house. Sentries were pacing up and down in front of it, and officers going in and out.

"Is that the headquarters of the French general?" he asked a townsman.

"Yes," and the man walked on with a muttered malediction.

A few minutes later several mounted officers rode out, and dashed off in haste in various directions.

"There is evidently something up," Fergus said to himself. "Perhaps they have got news of the Prussian approach."

In a quarter of an hour several general officers arrived, and entered the house. It was evident that a council of war had been summoned. Half an hour elapsed, and then a number of aides-de-camp and staff officers rode off in haste. A few minutes later, a trumpet sounded a regimental call, and then the assembly.

Before it had died away, similar calls echoed from all parts of the town. Soldiers ran hastily through the streets, mounted officers dashed in every direction, and the citizens came to their doors, in surprise at this sudden movement.

Fergus had no longer any doubt about the cause of the stir. The great thing, now, was to ascertain whether the army would advance to take up some strong position outside the town and oppose the Prussian advance, or whether they would march away.
